I really like the Asus Directcu II GTX570 cards. Why? Well they have better components and are equiped with more power phases than the reference cards...also they draw a little less watts...every little bit is a gain I guess...

My Mobo is Asus P8P67 DELUXE...I would like to SLI two triple-slots 570 directcu II cards on this board...will it fit?

IT seems like it will...I put a gtx260 in the top slot and it SEEMS like the is still 2 slot spaces before the next PCI-E slot on the mobo...

Are the PCI slots in the way? (slot connectors being a little higher than PCI-E slot connectors)..

According to my guesstimate, there would be a full empty slot between the top card's fan shroud aND the lower card's backplate...

When 3 Builds in total do the Exact same thing on the exact same games. I highly doubt 5 cards failed all at once.

ALthough yes, I do understand what you are saying. However the visable stuttering you see is not a failing card. I've never seen a card fail like that before, and its more prevelant in certain games over others.
